Previous PageTable Of ContentsNext Page


The NHSDA includes a series of questions that are based on the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) used to assess dependence on substances. It includes questions about health and emotional problems associated with substances used, attempts to cut down on use, tolerance, and other symptoms. Respondents are also asked to report on whether they had received treatment or counseling for a substance abuse problem. The following analysis is based on past year users of illicit drugs and alcohol. For this analysis the 1997 and 1998 NHSDA data were combined and average annual estimates are presented.

Of the 23.1 million persons who used an illicit drug in the past year, 1.9 million reported some health problem due to their illicit drug use, 3.5 million reported an emotional or psychological problem due to their drug use, and 4.1 million were dependent on an illicit drug. An estimated 963,000 had received treatment or counseling for their drug use (Figure 17).

An estimate d 1.1 million youths age 12-17 (26.8 percent of all past year illicit drug users in this age group) were dependent on an illicit drug, including 0.9 million dependent on marijuana. An estimated 175,000 youths had received treatment or counseling for their drug use.

9.7 million people were estimated to be dependent on alcohol, including 915,000 youths age 12-17. An estimated 1.7 million people (including 148,000 youths) reported receiving treatment or counseling for alcohol use.
